RSS
Feeds

RSS is a format for syndicating news and the content of news-like
sites, including major news sites like Wired, news-oriented
community sites like Slashdot, and personal weblogs. But it's
not just for news. Pretty much anything that can be broken
down into discrete items can be syndicated via RSS: the "recent
changes" page of a wiki, a changelog of CVS checkins,
even the revision history of a book. Once information about
each item is in RSS format, an RSS-aware program can check
the feed for changes and react to the changes in an appropriate
way.

RSS-aware programs called news aggregators are popular in
the weblogging community. Many weblogs make content available
in RSS. A news aggregator can help you keep up with all your
favorite weblogs by checking their RSS feeds and displaying
new items from each of them.
